| Abstract: | The effect of extended stationary contact on the shearing force has been investigated in the case of rubbers subjected to constant compressive deformation at high and low temperatures. The dependence of the shearing force on the logarithm of the stationary contact time is linear up to the moment of accumulation of 100% relative residual deformation. It is shown that the time-dependent processes that determine the values of the shearing forces can be intensified by raising the temperature. The results of the investigation can be used in predicting the shearing force in the case of rubbers in extended contact with metal under conditions of constant compressive strain.Laboratory for Problems in Polymer Physics, Lenin Moscow State Pedagogical Institute; Leningrad Branch of the Scientific-Research Institute of the Rubber Industry.
